Synthesis and applications of a new palladacycle as a high active catalyst in the Suzuki couplings

Di-μ-chlorido-bis{[4-chloro-2-(dimethylaminomethyl)phenyl-κ2C1,N]palladium(II)}

“…Since the discovery of cyclopalladated complexes (CPCs) a half a century ago, these organometallic compounds have found a plethora of applications (Morales-Morales, 2007;Joshaghani et al, 2008;Xu et al, 2009). We have reported the crystal structures of chiral acetate-bridged binuclear cyclopalladated complexes and the application of some cyclopalladated complexes of tertiary arylamines in coupling reactions (Yang et al, 2002;Zheng et al, 2003).…”

“…For cyclopalladated complexes (CPCs) of tertiary arylmines as efficient catalysts in coupling reactions, see: Morales-Morales (2007); Joshaghani et al (2008); Xu et al (2009) ;Yang et al (2002); Zheng et al (2003). For the crystal structures of related CPCs, see: Calmuschi-Cula et al (2005); Yang et al (2003); Zhou et al (2010).…”

Metal Catalyzed Suzuki-Miyaura Cross-Coupling– Efficient Methodology for Synthesis the Natural and non-Natural biological active Molecules

“…Many heterocycles such as arylated furans and thiophenes have been synthesized in high yield using this reaction scheme [56]. Being versatile in nature and demonstrating compatibility with functional groups, the Suzuki cross coupling reaction is the method of choice for reactions involving C-C bond formation [57]. In present study, a convenient approach for the synthesis of thiophene sulfonamide derivatives 159 via Suzuki cross coupling reaction is reported.…”

Investigation of the catalytic activity of a Pd/biphenyl-based phosphine system in the Ullmann homocoupling of aryl bromides

“…As shown in Table 1, the reaction rate is greatly affected by the kind of solvent used. Among the commonly used organic solvents, the best results were obtained with DMF (Table 1, entry 7) and in some extent with CH 3 NO 2 and DMSO (Table 1, entries 17,19). DMF has an important advantage which made them as a unique solvent.…”
